On install, package.json runs 'node preinstall.js || true', which collects os.hostname(), os.platform(), os.arch(), and the package name/version and POSTs them as JSON to a URL taken from the DC_CALLBACK_URL environment variable, defaulting to http://127.0.0.1:5656/exfil. The env-var override turns the loopback default into a functional attacker-configurable beacon that fires automatically on npm install and discloses installer host identifiers plus confirmation that the shadowed internal name resolved to this public artifact.\n\n---\n\nCredit: OpenSSF (source)","public_affected_ranges":["= 99.0.0"]}],"null_published_at":"2026-10-31T22:13:22.846Z","source_updated_at":"2026-10-25T15:31:43.000Z","source_disclosed_at":"2026-10-25T15:31:37.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:56:59.340Z"}],"next_cursor":null,"snapshot_revision":"42594"}
